C# Regular Expressions for Matching “ABAB”, “AABB”, “ABB”, “AAB”, “ABAC” and “ABCB&r
by drnickriviera in Programming Languages

by Steve O. in Development Tools & Services

Greetings,


for one of my applications I'm trying to implement an "Edit" menu. This menu usually has the standard-entries Undo, Cut, Copy and Paste.

I have a bunch of buttons named:


button1
button2
button3
etc.

Is there a way to basically do this?


pseudocode
for(int i = 1, i < 15, i++) {
button{i}.selected = YES;
}

This also goes for method calls, etc. I've often thought such a way of calling methods would be very convenient, but I d
